Filter by:The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.
To report closure rate, Best Corrected Visual Acuity (BCVA), Retinal Sensitivity (RS) and Fixation Stability (FS) of idiopathic Macular Holes (MH) randomized to Cover Group (CG) or Fill Group (FG) of the Inverted Internal Limiting Membrane (ILM) flap surgical procedure.
This study compares the anatomical and visual outcomes in a large series of patients affected by idiopathic macular holes larger than 400 µm treated using pars plana vitrectomy and gas tamponade combined with internal limiting membrane (ILM) peeling or the inverted internal limiting membrane flap technique. A part of the participants will receive internal limiting membrane peeling,whil the other will receive the inverted internal limiting membrane flap technique.
The aim of this study was to determine whether inverted ILM peeling technique could contribute to high reattachment and closure rates after vitrectomy in patients with myopic macular hole retinal detachment (MHRD) in comparison to no ILM peeling. This retrospective study will include 40 patients presenting by myopic macular hole retinal detachment. Exclusion criteria will include history of trauma, choroidal neovascularization, and the presence of a peripheral retinal break or proliferative vitreoretinopathy before the initial surgery. Subjects will be divided into 2 groups; Group 1 will include 20 patients that were treated by vitrectomy without ILM peeling and postoperative gas or silicone oil tamponade with or without cataract surgery. Group 2 will include 20 patients that were treated by vitrectomy with ILMflap technique and postoperative gas or silicone oil tamponade with or without cataract surgery.
This study will compare by swept-source optical coherence tomography (SS-OCT) the retinal morphology after inverted internal limiting membrane (I-ILM) flap vitreoretinal surgery for medium-to-large macular holes using infracyanine green (IFCG) vs brilliant blue G (BBG) dyeing. It is a single-center prospective, randomized study. One group of patients will undergo I-ILM vitrectomy with IFCG staining, the other vitrectomy with BBG staining. Postoperative twelve-month corrected distance visual acuity, macular hole closure rate, and SS-OCT parameters will be compared and statistically analyzed. The aim of the study is to verify if these parameters can be negatively affected by toxicity related to the use of one of the two dyes.
Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.
This is a prospective, interventional, consecutive case series conducted in Alexandria university. The aim of the study is to evaluate the therapeutic efficacy of human amniotic membrane in promoting closure of large macular holes.
To compare anatomic and functional results, and to evaluate postoperatively the healing process in 2 different techniques for the closure of the macular holes (MH)
Observing and describing the surgical effects of different extents of internal limiting membrane peeling combined with internal limiting membrane insertion for macular hole
The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.
